A bogie assembly for a rail vehicle comprises a bogie frame, two wheel axles supporting the bogie frame, a primary of a linear induction motor and two motor mounts. The two motor mounts are located proximate a different extremity of the primary and support the linear induction motor underneath the bogie frame. Each one of the two motor mounts has a bogie interface, a motor interface, a first spring, a conical spring, a core pin and a nut. The first spring is connected to the bogie interface on the bogie side while the conical spring is connected to the same bogie interface on the motor side. The core pin extends sequentially from the motor interface through the conical spring, then through the bogie interface and finally through the first spring where it is held in place by the nut on the other side of the first spring.

The present invention generally relates to a rail transport system having no internal drive, and in particular to an improved rail transport system for conveying bulk materials. The rail transport system includes horizontal and vertical drive stations that include a drive tire that rotates on a plane parallel to the track. In this arrangement, force is applied on a different plane than earlier systems, and the reaction force is separated out of the tensioning device. The improvements of the drive stations provide for a reduction of steel used in the system, improved manufacturability and, therefore, reduction in system component costs as compared to previous drive stations. Moreover, the drive stations allow for improved maintainability and access to the drive tires.

A device for connecting a cross member for receiving pivot pins on two lower longitudinal members of a car body for a rail vehicle. The cross member has a transversal part that connects the two longitudinal members to each other in the region of the connection, and a longitudinal part that extends to the closest car front. The lower longitudinal members extend over the complete length of the car body and consist of multi-chamber hollow profiles made of a fibre composite material. The number of chambers of the multi-chamber hollow profile of each longitudinal member is reduced in the region of the connection such that the wall material of at least one chamber was removed in such a way that the webs to the adjacent chambers are exposed. At these places, load-introducing elements engage, to which load-introducing elements the cross member is attached.
